To all whom it may concerns y Be it known vthat-I, WILLIAM BROTHERS, a citizen of the United States, residing atjCly, inthe county of York and State of Pennsylvania, have invented la certain 'new and useful Improvementin Charge-Forming Devices for Internal-Combustion Engines, of which the following isa full, clear, and 'exact description.'

' This Ainvention relates to chargeeforming devices for internal combustion engines, wherein gasolene or other volatile or vaporizable fluids, areused as the vapor-producing element.

The object of the invention is to provide a charge-former for internal-combustion engines of simple and economical construction, and 'effective operation, and `which is easily accessible for cleaning and repairing purposes.- A v In the accompanying drawings, illustrating the invention, 1n the several figures of which like parts are similarly designated,

Figure 1 is a sidelelevation. Fig.`2 is a vertical section, with the vaporizing coil broken away. Fig. 3 is a top plan view,y with'the vaporizing coil broken away.

The mixing chamber comprises a tube 1, having a coupling 2 at its upper end, and preferably a T-coupling 3 at its lower end. Secured. in-thel upper end of the coupling2 -in any suitable manner, is a valve 4, of any sultable construction, havlng its valve-stem` 5, projecting beyond the valvecasing and rovided with the hand-wheel 6. `As shown 1n Fig. 2,l the outlet .port 7 of the valve 4,. ,opens into the mixing chamber, and is ar-' ranged substantially in line with the longitudlnal aXis of said chamber. The opening 8 of the coupling 2 constitutes the air inlet for the mixing chamber. The hand-wheel 6 of the valve-stem is provided Iwith a seriesof notches orindentations V9.

1.0 is a plug screwthreaded into the bottom of the mixing chamber, and provided with a central bore or opening 1l.

Longitu linally ,arranged within the .miX-

ing chamber is the mixing core, comprising in its preferred form, a rod or bar l2 of metal or` other suitable material, having its lower endprovided with a serrated foot'13 supported uponthe plug 10 `and arranged above v the opening 11 thereofso as not to-fclose said opening. The upper end of the core rod 12 is constructed as a grooved head 14, slightly tapered,.and adapted to tor seat into the outlet port 7.of the valve 4. Between its ends, and commencing just below the airinlet opening S, the mixing core or rod 12 is provided lwith a series of sets of stationary baffles 15, arranged at suitable distances apart, equal or unequal, and preferably constructed as inclined fan-shaped blades, radiating'froin the core, the blades of each successive set being inclined reversely.

The. open stem 1'6 of the T-ooupling 3 constitutes the outlet for the mixing chamber,

' and suitably connected with this outlet, as

by a cou ling nut 17, is one end of a coil 1,8, of suitable length and any desired number of sections. nates at a point adjacent to the upper end of the mixing chamber, and preferably supported .by a clam ing member 19 engaging the upper ends ofpsaid coil and the mixing chamber, s ee Figs. -1 and 3.

As herein shown, the upper end of the coil is provided with a fitting 20 constituting a charge modifyingor diluting chamber, and having its lower end suitably connected with the terminal of the coil section, as by an elbow and couplin 21. The u per end of said chamber 20 is eft open, and) said chamber has a lateral charge outlet 22, which outlet is adapted to be connected with the cornbustion chamber of an engine-,in any suitable manner.

As herein shown, the clamping member 19 is provided with ears 23, in which is ivoted a cover .or lid 24, adapted to close t e o en upper end of the charge modifying or di ut- -ing chamber 20. The cover or lid 24 is prefn erably held to its seat by a spring 25, or said cover .or lid may be weighted for this urpose. The outer end of the cover or li 24 is adapted to be'connected in any suitable casing, is an arm 29l projecting beyond the The other end of this coil termij 55 of lthe engine, hrough its valve. \By this outer' ed e of the hand-wheel, and Asecured u von sai arm 29 and overhanging the hand- W eel G7 is a spring-finger 30, the end of which is adapted to engage one or the other of the are frictionally locked together.

notches or indentations 9 of said hand-wheel, whereby Vsaid arm 29 and the hand-wheel 6 A link 31 is connected with the arm 29 at its outer end, and extends to and is connected with the lid or cover 24, about centrally between its pivot and outer end, whereby the lid 'and said arm are simultaneously moved in the operation of thedevice. l

Grasolene or other suitable vaporizable fluid is fed to the valve 4, from asuitable tank or other sup ily, through an opening 32 in its casing, see

set" for supplying the desired quantity of asolene or other fluid, the engine is started 1n the usual manner. Upon opening the ,f valve 4, previous to the starting of the engine, the gasolene' or other fluid passes through the outlet 7 of the valve and. coming in contact with the end 14 of the mixing core 12, finds its way through the several grooves or passages therein,` and being thus initially separated. or divided gravitates down said core and spreads thereabout in a fine' film, and as it approaches the air inlet 8 of the mixing chamber, the suction stroke of the engine causes a rush of air into said inlet and about said core, and the air thus drawn in absorbs the filml of gasolene from the core,

Vthoroughly cleaning the core of the gasolene,

and thus preparing the core for the next succeeding charge of gasolene to be received and spread thereon ready for the next suction stroke ofthe engine. The mixture of air andpartly lYaporized fluid thus produced, is carried through the mixing cha ber and in contact with theseries ofbaffle an ,is thoroughly commingled. The mix ure then asses into the coil 18 Vand is retained there- 1n duringthe working stroke ofthe engine,

and in its passage through an'd retentibn in said coil becomes-thoroughly va orized and passes thence into the `combusti m chamber construction a d operation the gasolene or other volatile or vaporizable fluld and air are thoroughly mixed in passing through thc mixing chamber, and the fluid partly vaporized and during retention in and passage through the coil the partly vaporized fluid becomes thoroughly vaporized and expand-1 ed, and produces a charge which is very effective in operation.-

The valve 4 is normally open whenv the engine is running and may be set to deliver the desired quantity of gasolene according to the capacity of the engine, by turning the valve by hand and maintaining the valve in such position by placing the spring-finger 30 in one or the other of the notches or indentations 9 of the handwheel 6. When the apparatus ist hus set to suit theworking capacity of the engine, and should the engine exceed its engine will be brought into operation, and pulling upon rod 28, will lift or raise the cover or lid24 and thus admit air into the diluting chamber, and, thus the charge will be modified or diluted before entering the engine. Simultaneously with the movement of the cover or lid 24, the link 31 acts to turn the varm 29 and through the spring connection with the hand-wheel 6 of the valve, will turn the valve to modify or shut off` the supply of fluid to the mixing chamber. Thus it will be seen that the engine may be automatically controlled and maintained at a regular rateof speed according to the work required of it.

`-By the described control of air and fluid, the

predetermined speed, the governor of the invention to the exact details of construction herein shown and described, since it is obvious that the construction may be varied in many particulars and still be ithin the scope and principle of the inventilgn.-
